Music pack

A music pack is a fan-made collection of music intended to replace the music of either an IWAD or another PWAD of maps. Notable examples are the IDKFA music pack, the Plutonia MIDI Pack, and the Memento Mori soundtrack. Since the songs of the original Doom games were all MIDI files, many music packs are also collections of MIDIs. In this case, they are also known as a MIDI pack.

To use a music pack, the one method supported by both vanilla Doom and all source ports is creating a with the -file parameter. In the batch file, the music pack needs to be listed after a map PWAD that has its own music. Another useful item is the IDMUS cheat code that switches which song is played.
